| DRAWING ANGLES WITH SET SQUARES |
| V. Ryan © 2008 |
| |
| |
| Set squares are used in conjunction with T-squares to
draw accurate angles. There are two main types of set square. One has an
angle of 45 degrees and the other 30/60 degree angles. |

 |
| The 45 degree set square also has a 90 degree angle.
This can be used for drawing vertical lines. |
|
The 30/60 degree set square also has a 90 degree angle.
This set square can be used to draw 30, 60 or 90 degrees angles. |
| |
|
|
| |
| Set squares are only accurate if they are used along
with a T-square. The set square must rest on the T-square which should be
pushed against the edge of the board. If the T-square is not right against
the edge of the board (if there are even small gaps) lines drawn at an
angle will not be accurate. |
| |
 |
| |
| Common errors when using T-squares and set squares are
that gaps are allowed to develop between the T-square and the edge of the
board or the set square and the T-square. This leads to inaccurate drawing
with angles being incorrect. |

| Set up a piece of A4 paper on a drawing board using a
T-square to ensure the paper positioned correctly. Use clips to fix the
paper to the board. Draw a border and title block with the title being 30
DEGREES ANGLES. Place the title at the top of the page as well, in larger
BLOCK CAPITALS. |
| |
| Draw a number of lines at 30 degrees and then ‘flip’
the set square round to draw 30 degree lines in the opposite direction. |
| |
 |
| |
| Draw a number of lines at 60 degrees and then ‘flip’
the set square round to draw 60 degree lines in the opposite
direction. |
| |
 |
| |
| Adjustable set squares allow a range of angles to be
drawn accurately. They can be adjusted to a variety of angles which means
only one set square is required. It must still be used by resting
accurately on a T-square. |
